ElEgllfl-HEATED IRON.

Application filed September 22, 1926. Serial No. 187,052.

This invention relates to an improved steam heated iron of the type usedby tailors and the like employed for supplying mois; ture to the apparelwhile being pressed.

Briefly. the improved structure comprises ahollow body constructed toprovide amain steam chamber through which steam is circulated. togetherwith a special compartment or auxiliary chamber into which a separatesupply of steam is injected to moisten the article being acted on. Y

My primary aim isto generally improve upon steam-heated irons of thisclass by providing one of comparative simplicity and durability which isfurther characterized by such features as ease of machining andmanufacturing, low costof production, and efliciency in operation.

Other features and advantages will become apparent from the followingdescription and drawing. In the drawing: I

Figure 1 is-a view in section and elevation showing the improvedconstruction and arrangement of parts,

Fig. 2 is a bottom plan view of the same with portions broken away todisclose certain of the details more plainly.

Referring to the drawings in detail, it will be seen that the referencecharacter 1 designates a single metal casting of customary externalconfiguration. By the term cusexternal configuration, I mean a bodywhich is of substantially semi-ovate outline. and which includes smoothsubstantially flat bottom surrounded by a marginal upstanding rim. Thecasting is formed into a hollow body which is open at its top andprovided at said top with an inwardly extending flange 2. The bottom 3.which is flat for a considerable-portion of its area. is

formed with an integral inwardly extending conical portion pending boses 5 disposed at diametrically opposite points. A removable closureforming disk 6 is secured to these bosses by fastening screws 7' andthis disk is provided with annular rows of circumferentially spacedsteam central portion of the disk is substantially imperforate. The diskcooperates with the cone in providing a special steam chamber forsupplying moisture to the cloth being acted upon. Connected to the apexof the cone is an individual steam-supply pipe 9.

A removable cover or top plate 10 is fas- 4. The cone includes de-'discharge apertures 8. Thetened as at 11 to the flange 2 and suitablepacking is interposed between the parts toprovide a steam pipe joint.This cover is provided with upstanding standards 12 upon which a handgrip 13- is mounted-.- A main steam chamber circulating is thus formedaround the conical steam chamber. A separate steam. supply pipe 14extends into tl1is.main steam chamber and a discharge pipe 15 is alsolocated therein. The discharge end of the pipe 14 is located in prox:imity to the base portion of the cone 4:. The intake end of thedischarge pipe 15 is located atits remote point. The pipe 15 extends asat 16 on the exterior of the iron to a suitable source of discharge. Asuitable main steam supply pipe is indicated at 17 and this connectswith branches 18 and 19 on a special fitting, each branch being providedwlth a valve 20 and 21 respectively.

With the arrangement shown it is obvious that the steam supply passingthrough 011'. pipe 17 may be simultaneously injected into the mainchamber and the auxiliary conical chamber when the valves 20 and 21 areopen. However, the supply of steam may be divided by closing the valve21 for instance to keep the cloth substantially dry while heating thebody of the iron to a degree sufiicient to accomplish eflicientpressing.

A particular advantage to be borne in mind in connection with theimproved construction is that the respective steam chambers are entirelyseparate and independent from each other and since the steam is suppliedto the main chamber substantially continuously while the iron is in use,it is obvious that a considerable amount of moisture will collect inthis chamber. Inasmuch as it has no communication with the auxiliarymoistening chamber, however, it is obvious that rust and dirtaccumulation can not enter the small chamber and pass into and discolorthe cloth. This-scale and other extraneous matter which de osits in themain chamber can be removedli movable cover. It is also obvious that byhaving a removable plate for the conical chamber, any rust dep'csit maybe separately removed therefrom.

It is believed that by considering the description in connection withthe drawings, a clear understanding of advantages and construction ofthe improved iron will be.

had. and therefore, a more lengthy description is thought unnecessary.
